WHAT NUMBER MUST BE ADDED TO BOTH THE NUMERATOR AND DENOMENATOR OF 3/7 TO OBTAIN A FRACTION EQUAL TO 7/9?

yan [13]

Answer:

Add 22/63

Step-by-step explanation:

3/7 + n = 7/9

<u>Step 1: Subtract 3/7 from both sides</u>

3/7 + n - 3/7 = 7/9 - 3/7

n = 49/63 - 27/63

n = 22/63

Answer: Add 22/63

You weigh six packages and find the weights to be 19, 15, 35, 17, 33, and 31 ounces. If you include a package that weighs 39 oun

vodomira [7]

Answer:

Step-by-step explanation:

Mean & median of 6 packages:

15, 17, 19, 31, 33 , 35

Median = $\frac{19+31}{2}$

= $\frac{50}{2}$

= 25

$Mean = \frac{15+17+19+31+33+35}{6}\\\\=\frac{150}{6}\\=25$

Mean & median of 7 packages:

15,17,19,31,33,35,39

Median = 31

$Mean=\frac{19+15+35+17+33+31+39}{7}\\\\=\frac{189}{7}\\\\=27$

After including 39 ounce package, Median will increase more

if the length of the drawbridge, r, is 20 meters and the point p is 16 meters above the roadway , what is the distance d?

zhenek [66]

I'm assuming that the figure formed in this problem is a right angle. Thus, we need to use the Pythagorean theorem to get the distance or the hypotenuse.

Length = 20 meters
Height = 16 meters

a² + b² = c²

(20m)² + (16m)² = c²
400m² + 256m² = c²
656m² = c²
√656m² = √c²
25.61 m = c

The distance is 25.61 meters.

On the unit circle, which of the following angles has the terminal point coordinates (√2/2,-√2/2)

aleksandr82 [10.1K]

Answer:

Option B

Step-by-step explanation:

A unit circle means radius of the circle = 1 unit

Let a terminal point on the circle is (x, y) and angle between the point P and x-axis is θ.

Center of the circle is origin (0, 0).

Therefore, ordered pair representing the terminal point will be (OP×Cosθ, OP×Sinθ) = $(\frac{\sqrt{2} }{2},-\frac{\sqrt{2} }{2})$
